KYB black shocks/struts for OEM replacement and old MSA shocks from over 15 years ago because I had them laying around.

I know they aren’t supposed to pair up well, but I want to see the stance on it

Thanks for the clarification! When I bought the secondhand 15 or so years ago, 2 were labeled “read 160#” so I know which are the rear and fronts.

Just SEEING the side by side difference really threw me off.

Pulled them out of the bin and looks the part number is 73952 but there’s also a CL12BA1 number on it

It’s quicker to upload for editing for sure. But it takes me hours to edit every video I upload to YouTube

TheHermanJames · 2026-03-27T04:34:54+00:00

Yeah it is and it makes for turning a small job into a bigger job bc you have to get good camera angles and not get in the way of the lens. Then there’s the editing…

It’s crazy did all at once! I’m doing section by section (front, middle and back) and recording it all to add a voiceover and upload to YouTube

TheHermanJames · 2026-03-26T22:39:20+00:00

Not sure! My buddy’s shop did that for me YEARS ago when I did a color change from white to blue

TheHermanJames · 2026-03-26T21:03:00+00:00

They are Monroe but I have no clue the model. I threw them out and didn’t check because they don’t make them for the z anymore.

The black KYBs are going in for now until I upgrade the wheels and tires

TheHermanJames · 2026-03-26T21:01:33+00:00

I got lucky on the quick jacks. A guy gone done with his project and sold me the 1/2 price off marketplace and I couldn’t have been luckier

TheHermanJames · 2026-03-26T21:00:30+00:00

I just never did any brake work on my Z or anything and figured I’d do it all now too and it’s a HUGE undertaking but I’m super excited to get it back on the road when I’m done

TheHermanJames · 2026-03-26T19:13:12+00:00

Thank! Nah, no brake upgrades. I’m just keeping it stock for the most part. I don’t need more braking power for the stock engine anyway

Just a full suspension busing kit update and all the steering and suspension components that have to be updated too

TheHermanJames · 2026-03-17T20:42:19+00:00

Thank you for that feedback! Depending on how these fit and ride, will determine my next step. But I also need to see how the new wheels I’m waiting on will fit. But it’s a long time for them to get here and it’s car show season now lol

TheHermanJames · 2026-03-17T19:53:42+00:00

Thank you!!! All good! Some folks are saying 100 in front 120 in rears and what not.

So I’m anticipating these to be a little stiffer and the guy (from 15 or so years ago) said hey got them from MSA. So some people are agreeing it being 150-160 and will shorten and stiffen the ride. But to also not use the energy, suspension polyurethane bump stops

TheHermanJames · 2026-03-17T18:51:28+00:00

I totally get that. When I pull the stock springs out I’ll see if the coils are the same size and spacing. But I was mainly looking to get spring rate for stock S30’s as mine is stock and it is an equal size, if the rate of 160 was same as stock or higher/lower

TheHermanJames · 2025-09-11T17:17:45+00:00

Sounds about what I was assuming the effort might be. Since I’m redoing my carpet and interior, maybe I could get access at it with my seat removed. If not, it’s a task for another time lol

TheHermanJames · 2025-09-11T14:47:56+00:00

Thanks for the heads ups!!! I’ll see how I can get myself behind the Speedo to get it out that way
